Through implant patient registry it was learned a 19mm 11500a aortic valve was explanted after implant duration of three (3) years, 10 months, due to unknown reasons.The explanted device was replaced with a 21mm 11060a aortic valved conduit.Edwards lifesciences maintains an implant patient registry.This registry is a patient tracking mechanism for serialized edwards implantable devices (bioprosthetic heart valves and annuloplasty rings), rather than a true post-market surveillance registry.Through the registry, edwards is notified when these devices are implanted.In addition, patient and/or device status may be reported to the registry via the implantation data cards.The information is received from various sources (e.G.Surgeon, hospital, and patient family members) and is not received in the form of a conventional customer complaint.The information reported may or may not be related to the edwards device.

The device was not returned to edwards for evaluation.Attempts to retrieve the device and additional information is in process.The investigation is still in progress; therefore, a conclusion has yet to be established.A supplemental report will be submitted accordingly upon investigation completion.Edwards will continue to review and monitor all events.Trends are monitored on a monthly basis and if action is required, appropriate investigation will be performed.

Through implant patient registry it was learned a 19mm 11500a aortic valve in aortic position was explanted after implant duration of three (3) years, 10 months, and 18 days due prosthetic valve stenosis secondary to infective endocarditis.The explanted device was replaced with a 21mm 11060a aortic valved conduit.Per medical records the patient initially presented with right sided weakness concerning for cva, and diarrhea.Workup revealed ct of head negative, no acute neurological process, pneumonia, possible peri-annular abscess, severe stenosis, moderate mr, and possible pvl.The patient was hospitalized for approximately three weeks, treated and sent home on antibiotics.Two weeks later the patient was admitted with fever chills, confused with delirium, paraplegia of the rue, hr in the 40s and diagnosed with sepsis and infective endocarditis.A tee showed rocking of the aortic valve, severe as and mobile mass in the ventricular side consistent with vegetation, aortic annular abscess, and moderate regurgitation, cath showed no significant cad.The 19mm 11500a valve was found to be heavily calcified at surgery, there was noted to be a large abscess involving the annulus of the aortic valve and the entire right coronary sinus and right coronary ostia.Due to large amount of inflammation it was impossible to mobilise the left coronary ostia for subsequent anastomosis to the hemashield graft.The patient underwent an aortic root replacement using a 21 mm 11060a and reimplantation of the right coronary ostia and bypass to the obtuse marginal and right coronary artery using reverse autogenous saphenous vein and cabg to the anterior descending using the lima.The aortic cross clamp was removed and there was brisk hemorrhage from the distal suture line of the graft and the ascending aorta.Cpb was resumed and an anastomosis repair performed with a separate piece of 21mm graft.The patient was briefly weaned from cpb, however, the left and right ventricles were profoundly hypokinetic, the patient underwent further complex coronary bypass using internal mammary segments in an effort to supply blood flow to the lv.A tee showed excellent left ventricular and right ventricular function.The patient was weaned from cpb.After closing the chest and then removing the drapes , the endotracheal tube was noted to be malposition which resulted in profound hypoxemia due to inadequate ventilation and subsequent cardiac arrest.The sternum was reopened, the patient re-cannulated and placed back on cpb.Attempts to discontinue bypass were only marginally successful and the patient was placed on ecmo and transferred to a higher level of care.At time of transfer the patient was stable on vasopressin and levophed.Pathology: aortic valve- fibrin with dense acute and chronic inflammation.
